The 787 is the replacement for the 767. They do need a good 757 replacement though. Stretching out the 737 again and again...well we know how that went.
i completely agree on stretching the 737. The 737 needs to be replaced, not stretched yet again.
On the 787, it was my understanding that because of its capabilities, its just too expensive an aircraft for shorter routes.
There is an A330-800neo, but only 10 orders for it right now according to Wikipedia. There is no A330-700neo though.
I do agree that Delta will never touch the MAX after this fiasco. That one plane single handedly destroyed a lot of Boeing's reputation.
There has been some speculation about an A330 600 or 700 that would be similar in size to the A300. Also discussion about the A330-800 made into a shorter range more efficient version.
The 737 has been eating into Boeing's reputation for the past 15 years.
I’m sure delta examines its options with any new model that comes on the market. I’m not sure they are in an immediate need of a plane this size though.
